1. Can you change the water in the fish tank every day? It is impossible to change the water in the fish tank every day. Although the water body can be kept clear, the especially clear water is not suitable for fish farming. Usually, water should be changed once a week. If the filtration system in the cylinder is powerful, it can also be changed once every two weeks. In addition, we should pay attention to the observation of the water body. If it is found to be turbid, we should change the water for it as soon as possible.
2. What's the harm of changing water too frequently1. Unstable water quality: If changing water too frequently, new water and old water will be exchanged constantly, which will lead to unstable water body and be very unfavorable to fish health. It should be noted that there are not only fish but also some beneficial bacteria in the water, and the unstable water quality will also threaten their survival.
2. Fish don't adapt: Frequent water change will cause new water to stimulate fish to some extent, which will make fish unable to adapt to the environment. In severe cases, it will also cause stress reaction and even lead to their death. Of course, we should not only control the frequency of water change, but also pay attention to the amount of water change, and don't change too much every time.
3, reduction of beneficial bacteria: fish culture should first raise water, and beneficial bacteria in water are very important, especially nitrifying bacteria. If water is changed frequently, this bacteria cannot grow and reproduce, thus reducing the conversion efficiency of ammonia nitrogen, thus fish are more likely to be poisoned and die.
